Author Notes: I’m loving baking more for my dinner this winter than for my dessert. This onion tarte tatin makes a perfect dinner, alongside a crisp salad. I prefer to make this in a 12-inch skillet for maximum onion coverage, and to make more servings, but the recipe can easily be lessened or tweaked slightly if you have a smaller skillet (just use less onions and make your puff pastry round smaller).
Featured In: An Unexpected, Ultra-Caramelized Take on Tarte Tatin —Erin McDowell
Makes one 12-inch tarte tatin
tablespoons unsalted butter
small onions, peeled, stem end left in tact, and cut in half
kosher salt and freshly ground black pepper
tablespoon balsamic vinegar
2 sprigs rosemary
4 sprigs thyme
one 8-10 ounce sheet puff pastry, thawed if frozen
parmesan cheese (optional, for garnishing)
- Preheat the oven to 400º F. Have ready a 12-inch oven-safe skillet, preferably cast iron.
- Place the skillet over medium heat, melt the butter. Add the onions, rounded halves downward in the skillet. Arrange the onions as tightly as possible to fill the whole pan (remember, they will shrink as they cook). Cook, undisturbed, until the onions have softened slightly and begun to brown, 12-15 minutes.
- Gently flip the onions and season with salt and pepper, flip again so the browned side is down. Add the sherry and balsamic vinegar and bring to a simmer. Cook until reduced slightly 1-2 minutes. Add the herb sprigs in between the onions.
- Transfer the skillet to the oven and roast until the onions are golden and tender, 15-20 minutes more.
- While the onions cook, roll out the puff pastry on a lightly floured surface to flatten. Cut a circle about the size of the base of the skillet (totally ok to freehand here, no need to be perfect). Dock a few times with a fork.
- Remove the skillet from the oven, and use a fork or pair of tongs to push the onions together slightly—this should be easier now that they’ve softened. Gently drape the pastry over the onions, folding in a little at the edges to encase the onions.
- Return the pan to the oven and bake until the pastry is very golden brown, 20-25 minutes. Remove from the oven and cool for 5 minutes.
- Invert the skillet onto a cutting board to unmold the tarte tatin. Let cool for 5 minutes more. If using, serve with a generous grating of parmesan cheese.
